Problem 23.4

Consider the following three complexes:

(Complex 1) $$\left[\mathrm{Co}\left(\mathrm{NH}_{3}\right)_{5} \mathrm{SCN}\right]^{2+}$$

(Complex 2) $$\left[\mathrm{Co}\left(\mathrm{NH}_{3}\right)_{3} \mathrm{Cl}_{3}\right]^{2+}$$

(Complex 3) $$\mathrm{CoClBr} \cdot 5 \mathrm{NH}_{3}$$

Which of the three complexes can have

(a) geometric isomers,

(c) optical isomers,

(d) coordination-sphere isomers?

Text Transcription:

[Co(NH3)5SCN] 2+

[Co(NH3)3Cl34]+

CoClBr \cdot 5NH3

Step-by-Step Solution:

Step 1 of 5) In ferromagnetic, ferrimagnetic, and antiferromagnetic substances, the unpaired electron spins on atoms in a solid are affected by spins on neighboring atoms. In a ferromagnetic substance the spins all point in the same direction. In an antiferromagnetic substance the spins point in opposite directions and cancel one another. In a ferrimagnetic substance the spins point in opposite directions but do not fully cancel. Ferromagnetic and ferrimagnetic substances are used to make permanent magnets.Coordination compounds are substances that contain metal complexes. Metal complexes contain metal ions bonded to several surrounding anions or molecules known as ligands. The metal ion and its ligands make up the coordination sphere of the complex. The number of atoms attached to the metal ion is the coordination number of the metal ion. The most common coordination numbers are 4 and 6; the most common coordination geometries are tetrahedral, square planar, and octahedral.Ligands that occupy only one site in a coordination sphere are called monodentate ligands.
